The TeleTouch 27" USB Touch-Screen Multiviewer works in conjunction with the AV Bridge MatrixMIX Multipurpose AV Switcher. The touchscreen allows all presets and camera positions to be displayed and activated by touching the image itself. The multiviewer function of the AV Bridge MatrixMIX Switcher can be configured to display up to six input windows and two larger "Preview" and "Program" windows with red and green tally window borders. In addition, each camera input can have up to 12 stored "video thumbnail" preset camera shots.
